When I visited family in Holland in October 2023, I visited Ton van Munsteren. He is a prolific designer and has many models published in British model magazines. The best way to describe him is to call him Holland's Laddie Mikulasko*.
Ton had just designed and built the Box Fly 20 and gave me a kit. I had to cut the pieces to fit them into my suitcase.
The first step was to re-glue all the cut pieces. I pinned one piece to the board and aligned the other half by using a steel edge to make it straight.
Will let them cure overnight before starting to assemble the plane.

1) photo of my visit to Ton's house and shop. The plane is in the foreground.
2) the kit as given to me
3) all the pieces were nicely laser cut.
4) the pieces I had cut apart were glued together. Note the metal ruler used to make sure the pieces were straight.

* Laddie flies with the Burlington group and has many designs published in RCM magazine. He designed the Force 1, Laker, Northstar and Easy 100 put out by Balsa USA.
Looks like a fun kit to build.
Make sure you do not end up with 2 right sides as the picture indicates. :D
Yes, Guy.
Before I started building it I flipped one fuse side over.
Sounds like you speak from experience.... but so do I! 8)
This is not a kit. It is a 3D puzzle. Formers are marked on the plans and the formers have laser numbering (F1- F11) but the numbers do not match the plans. The laser cutting is so precise they only fit one way.
Frank
ps: I had to line them up that way to join them because the steel ruler had to be on the bottom of each piece. Otherwise I could not have fit all the pieces on the board in one sitting..
starting to assemble the fuse.
F.
- basic fuse build finished. The motor is 450 watts for a plane requiring 400 watts. Just about right.
- tail feathers glued. Just need to be sanded.
- wing building finished on one side. Note the 1/4" square balsa near the trailing edge (at the point of the knife). This is a symmetrical wing shape. By placing this 1/4" square on an angle, I am building in "wash-out". (trailing edge at the tip higher than the leading edge for stall protection).
- the hatch is finished. Magnetic hold-downs still have to be added.
Next: the other wing half. It will be built onto this finished half.
Frank
- Building the second wing half- onto the finished first half.
- adding the shear webs
- cut out the canopy and build the headrest out of 8 pieces laminated.

Why is the headrest have white lines in the picture #5311?
Are these for alignment?

The dark parts are where the wood was laser cut (burnt), and the white (balsa wood colour) is where the wood was still attached to the sheet.
Thank you Michael! ;D

Guy, I decided to arc the headrest area to match the cockpit cut-out. It cradles the pilot's head during high speed turns. A built-in HANS* device. 8)
